Definitions

  • the present invention relates to a device intended to transform heat into mechanical energy collected on a rotating shaft.
  • this machine will be a wind turbine
  • the power which it picks up varies like the cube of the wind speed, under the conditions of optimal efficiency which are characterized by operation at constant specific speed, this representing the ratio of the circumferential speed of the rotor to the wind speed.
  • the energy converter should ideally dissipate a power proportional to the cube of the speed of rotation of the shaft and, consequently, have a resistive torque proportional to the square of this speed of rotation.
  • the subject of the present invention is a converter of kinetic energy for rotation to heat free from the drawbacks of previous devices, which is particularly reliable and makes it possible to give the resistive torque which characterizes it a value varying according to a predetermined law, for example as the square of the speed of the drive shaft.
  • the converter according to the invention essentially consists of a multipolar rotor with permanent magnets, a stator comprising an electrically conductive wall subjected to the magnetic induction generated by the rotation of the permanent magnets and thus producing a resistant torque by generation of eddy currents and an exchanger heat and is characterized in that said electrically conductive wall delimits, inside the stator, said heat transfer fluid circuit.
  • the figured device comprises a rotor mechanically linked to the primary drive shaft 1.
  • the latter consists for example of the output shaft of a speed multiplier whose input shaft is the shaft of a vertical axis wind turbine.
  • the primary shaft thus rotates at 900 rpm for example.
  • the rotor is constituted by a plurality of radial permanent magnets 2, the external pole faces of which are covered with mild steel parts 3.
  • the rotor is advantageously constituted by these elements and a coating of moldable material 4, so as to have an external surface smooth cylindrical. When it turns, it produces a magnetic induction which sweeps the space which surrounds it and is therefore likely to create: in this space, within parts of material with low resistivity, F oucault currents. This property is implemented to generate, in the very walls of a heat exchanger inside which a fluid is circulated, calories which will raise the temperature of this fluid.
  • Said heat exchanger is constituted, in the illustrated embodiment, by a cylindrical housing 5 whose material has a low electrical resistivity (copper or light alloy for example) inside which is formed a helical duct 6 so as to that the circulating fluid is found, during a fairly long journey, subjected to contact with hot walls whose temperature is linked to the intensity of the Joule effect produced by the eddy currents specified above.
  • This fluid which will for example be water, will heat up, in a time of the order of a minute, passing from a temperature in the region of 15 ° C for example to a temperature between 50 and 70 ° vs.
  • the circulation of the fluid can be continuous.
  • the housing 5 is advantageously made of two coaxial parts, one of which 5a constitutes the cylindrical inner wall of the exchanger and its upper annular wall, while the other 5b constitutes the cylindrical outer wall of the exchanger and its lower annular wall .
  • a mild steel magnetic yoke 7 is advantageously placed around the cylindrical housing of the exchanger, so as to avoid the dispersion of the magnetic field and thus increase its intensity at the exchanger. It can be rotated. Insofar as it is not driven in rotation (illustrated embodiment), it is also the seat of eddy currents created by the rotating induction of the rotor, but these are much weaker than those produced in the walls of the exchanger, because the resistivity of mild steel is much higher than that of the material used to form the walls of the exchanger.
  • the heating of the cylinder head which is in contact with the exchanger, contributes to the heating of the fluid and is not therefore not the cause of a loss of performance of the device.
  • the device is mounted between a base 11 and an upper plate 12 interconnected by three columns 13, 14, 15 and by three guide rods 16, 17,18.
  • the rotor is supported by two bearings 19 and 20 respectively mounted in the plate 12 and another fixed support plate 21.
  • the integral exchanger-cylinder head assembly is slidably mounted on the rods 16, 17, 18, by means of ball bushings such as 22, 23.
  • the displacement in one direction or the other of said assembly along the guide rods is caused by a pinion 24 which cooperates with a rack 10 fixed to the cylinder head 7 according to an external generator thereof.
  • said resistive torque C is shown as a function of the speed of rotation, expressed in revolutions per minute.
  • the curve t 1 corresponds to the relative position of the exchanger-cylinder head assembly and of the rotor shown diagrammatically in FIG. 5; the curve l 2 , in the position shown diagrammatically in FIG. 6; the curve l 3 , at the position shown schematically in Figure 7 and the curve l 4 , at the position shown schematically in Figure 8.
  • a tachometer device 8 which provides control information for a pinion drive member comprising an electric motor 9.
  • the position of the exchanger-cylinder head assembly is therefore controlled by the speed of rotation of the primary shaft, the control law, programmed in the drive member, being such that the resistive torque applied to the primary shaft varies between 0 and the maximum value according to a curve defined a priori and, for example , varying as the square of the speed of rotation, that is to say of parabolic shape (dotted curve in Figure 4).
  • the arrangement which has just been described is of the cylindrical type with symmetry of revolution. It is obvious that other provisions can be envisaged.
  • the magnetic rotor instead of having radial poles, could be constituted so as to create an induction parallel to its axis and which would be closed by a circular, coaxial flat part, located a short distance from one of its extremities. Between the rotor and. this room we could have an exchanger where the water would circulate between the two planes they define.
